    [00:00:02] Welcome to AppSec Builders, the podcast for practitioners building modern AppSec hosted by JB Aviat.


    Jb Aviat: [00:00:14] So welcome to this episode of AppSec Builders. Today I'm proud to interview John Stevens. So, John is the founding principle at Aedify where he advises product security firms. John, before that, you led ZeroNorth as a CTO and before that you were leading as co-CTO at the Cigital firm. Welcome, John.


    John Steven: [00:00:36] Hello, how are you? Thanks for having me.


    Jb Aviat: [00:00:38] I'm great, thanks for joining. So John, another thing that you've done is that you co-authored BSIMM, so could you let us know what it is and how it can be a useful tool to AppSec builders?


    John Steven: [00:00:50] Yeah, it's worth clarifying because it's frequently misunderstood. The BSIMM is the building security in maturity model observational study. We went out and over a period of 11 years we've studied about two hundred and over two hundred firms and asked the question, what do you actually do to build your security initiative and to secure your software? And it doesn't prescribe what to do, but you can use it to look at what firms that are within your vertical or that look similar to you in terms of maturity, are doing with their time and money, and decide whether or not you want to replicate those behaviours or cut your own.


    Jb Aviat: [00:01:29] So you are interviewing like CISO application security practitioners, developers like every actor of the security game.


    John Steven: [00:01:38] Yes. Historically, the list has looked like what you described. What was interesting to us about the last two years of this study is that when we began talking with the CISO, they'd say, oh, you need to talk to the VP of Cloud on this, or actually you need to talk to the SREs and to to delivery or to the VP of engineering. The people we had to talk to fundamentally changed over the last two years. And that was a key finding that we we wrote about this year, that the people doing the work of security were shifting from the security group to the engineering, digital transformation and cloud groups.

    In this episode of AppSec Builders, I'm joined by New Relic Principal Engineer and AWS Serverless Hero, Erica Windisch. Erica has decades of experience building developer and operational tooling to serverless applications. We discuss all things serverless including why you should care about serverless security, designing app security when migrating to a serverless environment, how to scale your app security with serverless and much more.
    About Erica:
    Erica is a Principal Engineer at New Relic and previously a founder at IO pipe. Erica has extensive experience in building developer and operational tooling to serverless applications. Erica also has more than 17 years of experience designing and building cloud infrastructure management solutions.

    Transcript for Serverless Security with Erica Windisch
    [00:00:02] Welcome to AppSec Builders, the podcast for Practitioners Building Modern AppSec hosted by JB Aviat.
    Jb Aviat: [00:00:14] Welcome to this episode of AppSec Builders today I'm proud to receive Erica Windisch, we will discuss about serverless and serverless security. Welcome, Erica.


    Erica Windisch: [00:00:24] Hi.


    Jb Aviat: [00:00:26] So Erica you you are an architect and principal engineer at New Relic, you are also an AWS serverless hero previously you were founder at IO Pipe, an before that were security engineer at Docker. Right?


    Erica Windisch: [00:00:41] Ah correct yeah.


    Jb Aviat: [00:00:42] So thank you so much for joining us today, Erica. I'm really excited to have you as a guest today.


    Erica Windisch: [00:00:50] Thank you for having me.


    Jb Aviat: [00:00:51] So, Erica, Serverless as an AWS serverless hero, I guess you know almost everything and you are very, very aware of what's happening in the serverless world. Before we dive in, like some AWS specificities, maybe you could remind us what is serverless and how does it differ from the traditional world, especially from a security standpoint?


    Erica Windisch: [00:01:14] Absolutely. So, I mean, my background, it's not just Docker, it's building open stack. It's building web hosting services. And, you know, this is an evolving ecosystem that, I mean, in the 2000s was, you know, as simple or as hard as taking your content and uploading it to a remote server and running your application to as complex as running your own servers. Right. And these, of course, are options that are available to you now. But increasingly, developers are moving towards dev ops. They're using containers. They are finding that CI/CD and deployments and all of these things are useful tools for the organizations to move quickly and operating physical machines as pets, as we would call it, versus cattle, which as a vegan is probably not the best metaphor. But, you know, over this time, we've been increasingly going higher level and operating and deploying and building at higher level layers. And serverless is that highest layer in a sense where rather than building a micro service is shipping a service that runs on a VM in a container and a host that you have to manage and operate, even if that's part of a larger Kubernetes cluster.


    Erica Windisch: [00:02:33] Instead, you just take your application and you give it to your cloud provider and your cloud provider runs it for you. There's a lot of advantages to this, largely that the platform is fully managed for you to a large degree. You know, you don't have to maintain operating system patches. You don't have to maintain Kernels. You don't have to do anything other than operate your application. And really, the biggest disadvantages to this are that you do lose control of manag

    Episode 3 Transcript
    Jb: [00:00:02] Welcome to AppSec Builders, the podcast for Practitioners Building Modern AppSec hosted by JB Aviat.
    Jb: [00:00:14] Welcome to the third episode of AppSec Builders today I'm proud to receive Emilio Escobar, who's CISO at DataDog. Welcome and good morning, Emilio.


    Emilio: [00:00:24] Good morning. Excited to be here. Thanks for having me.


    Jb: [00:00:24] Thanks lot for joining us. So you recently joined DataDog as a CISO, but you have a broad experience as a security leader, at DataDog today. But before that, Hulu, Sony, and I think you are also the maintainer of a famous tool for security geeks like this, which is Ettercap, right?


    Emilio: [00:00:48] Yeah, that is correct. I'm one of the three main maintainers of it, and we've been doing it for about nine years already.


    Jb: [00:00:56] Do you want to share a bit what Ettercap is about? I used it regularly into pentests'. That's an amazing tool.


    Emilio: [00:01:02] Sure. Ettercap has been around for a long, long time, I think, since 2006, and it had slowly died down in around like maybe two thousand eight, two thousand nine. But it is a man in the middle attack tool. It's leveraged by a lot of pentesters for doing man in the middle attack to their customers and trying to obtain credentials for for services like SSH Telnet and what have you. How I got started with it was that when I worked at Accuvant Labs, I was a pentester, one of my colleagues was using it or trying to use it for an engagement that he was working on. And he was running into some, some bugs. And he reached out to me and asked me if I knew how to code in C. I said yes. And he's like, I'll give you five hundred dollars for if you solve these two for each of these two bugs that, that I'm running into. So looking at the code, I was able to fix the issues that he was running into. I never got that thousand dollars back. But what that started was the conversation between him and I. This is Eric Meilin, who I believe is that BlackBerry now about like, hey, should we actually resume the support for Ettercap? We wanted it to work well in MacOS. We wanted IPv6 support. We wanted all these new features that it wasn't supporting. And we reach out to ALoR and NaGA the original authors and they were gracious enough to allow us to to run with it as long as we kept it open source. Right. And that was the commitment that we gave them. So fast forward nine years. We've we've added a few versions. Now, I'm less involved in the coding because I really don't just don't have the time for it, b
